French meat casserole-Мясо по-Французски

This meat casserole has nothing to do with French kitchen.This dish is called French meat because it was the first dish that was prepared for Russian Graf Orlov in Paris, favorites of Ekaterina.The original dish was named “Orlovskiy veal” which had layers of veal,potatoes,onions and mushrooms that was baked in bechamel sauce and topped with cheese.Years down the road this recipe was simplified with beef, chicken and pork. And the bechamel sauce was exchanged for cream,mayonnaise or sour cream.
This dish is one our family favorites that I remember making since I was a child.It was always served on holidays and special days.
There is few variations to this dish, like including sliced potatoes or mushrooms(sauteed). I don’t really like it that way, but feel free to add them if you do like it.

1 1/5 beef tri -tip sliced
1 medium onion or 2 small onions chopped
3 1/2- 4 cups shredded mozzarella cheese
salt and pepper
8×11 glass baking dish

Heat oven to 375 degrees.
Pound the meat slices on both sides.

Arrange everything in this order:
-Sprinkle some onions to the bottom of the dish.
-tenderized meat
-salt & pepper-
Repeat the steps for next layer or two (total of up to 3 layers)
Spray foil with nonstick cooking spray and cover the dish with the sprayed side so the cheese won’t stick to the foil.
Bake for 2 hours or when the meat is very tender.
Serve with your favorite side, My favorite is mashed potatoes ot buckwheat.
